Alfonso Benito Calvo holds a Ph.D. in Geological Sciences from the Complutense University of Madrid, where he completed his doctoral thesis on the evolution and reconstruction of palaeolandscapes in the Sierra de Atapuerca. Since 2008, he is a researcher at the CENIEH, where he carries out activities related to the geological investigation of palaeolithic sites. In his research, he applies geomorphological, stratigraphic and sedimentological techniques to analyze the site formation and reconstruct the landscapes and processes that characterized the physical environment of human occupations during Pliocene and Quaternary. In addition, he has specialized in the use of new 2D, 3D and 4D spatial analysis, to unravel the site formation processes and study  their remains. Currently, he is working on numerous projects spread across Spain, Africa and Asia.
